Per,

Reading your wording again; you might have a point if you mean that
it is a new specification and that older software probably doesn't
have any knowledge of the special handling of _this_ header.
If the header was folded in the middle of a string, by an other
program without knowledge of this specification, that certainly
would be against rfc2822 specifications.

But maybe you should say that the new protocol or specification
would be broken if it didn't anticipate on to be expected actions
of older solftware that isn't aware of the new specs.

And a robust implementation of a new specification shouldn't take
any risk and do the proper folding right from the beginning
as soon as the header is inserted.
So I think it's likely that the folding was done by the program
that inserted the header
